Ringtones are little melodies and tunes created to give a
unique sound
to the GSM phone when the phone is ringing. Ringtones can be composed with an
appropriate editor and they can be sent as SMS messages.

Support for operator logos in Ozeki NG - SMS Gateway

When a ringtone is sent as an SMS message, it is represented as a bitstream.
This bitstream can be pictured as a set of hexadecimal numbers.

For example:

024A3A51D195CDD004001B20550590610560558550548540820849900000

The bit string contains the following sections:

00000010

<command-length> Number of command parts

Sending a ringtone in SMS

To send a ringtone message with Ozeki NG - SMS Gateway,
you need to specify a message type which tells the software that the message
body contains a ringtone. To send the above example, you would use the following
message type: SMS:RINGTONE. In this case, the message type is made
up of two sections. The first section tells the message server that this is an
SMS message. This way only the service providers supporting this type of SMS will
be considered to deliver the message. The second section is used by the service
provider to use the ringtone encoder.
This encoder will create the protocol data unit (PDU) that will be sent as an SMS
message.

Example:

If you use
the Database user to send and receive
SMS messages with Ozeki NG - SMS Gateway,
you can use the following SQL statement to send a ringtone message:
insert into ozekimessageout (receiver,msgtype,msg,status) values ('+36205222245',
'SMS:RINGTONE','024A3A51D195CDD004001B20550590610560558550548540820849900000','send');
